I have played around quite a bit with RTF. It is a huge spec; and Word, as usual, is abusing it all the way. Stay away from Word if you can!

WordPad however is pretty decent, and it can display (and to some extent let you modify) things you can't create with WordPad, e.g. tables.

FWIW: to concatenate two RTF documents, put one in an RTB, then paste the second one into it, then save.

PS: don't consider an RTB for 10MB+ documents, it sucks big time.

I've never used an RTB but can't you insert your item identifier tokens into the text, detect the position of the user click/selection and just work back through the text to find the token

WebBrowser control reset

Hi
I've got a desktop application that uses a WebBrowser control to let users access their Gmail accounts. I have multiple users though, and every time a users logs out of the desktop application, and a new user logs in, the WebBrowser goes to the previous users email account. How can I reset the the WebBrowser completely so that it navigates to the Gmail homepage? I tried clearing the cookies as well as the temporary internet files folder (I tried this programmatically in code as well as using the Windows way), but still no luck. It still navigates to the previous users email account. What is strange though is that when I close down the desktop application completely and run it again, the WebBrowser navigates to the Gmail homepage.

Any ideas?

after the user finished, set the instance of the web browser to null then call the garbage collector System.GC.Collect();

Thanks for the quick reply.

Okay so now when the next user tries to access his/her email, I call the following again:

this.browserGmail = new System.Windows.Forms.WebBrowser();

this.browserGmail.Location = new System.Drawing.Point(5, 53);
this.browserGmail.MinimumSize = new System.Drawing.Size(20, 20);
this.browserGmail.Name = "browserGmail";
this.browserGmail.Size = new System.Drawing.Size(914, 616);
this.browserGmail.TabIndex = 4;

browserGmail.Navigate("mail.google.com/mail");

This seems to work, but the browser doesn't get directed to any page, it just shows me a white screen?

So I tried:

browserGmail.CreateControl();
browserGmail.Update();

Still no luck

Passing string to stored procedure.

I have a long string which I need to check its existence in database. The string is follows:

string str = AU000AC20095=YBAX ,XS0088980494=MLIL,IT0003953350=HVBT

To make it sql compliant like.

Following is the sql query I need to execute:

SELECT ISIN_Universe_Id,ISIN,RIC,DateCreated from ISIN_Universe where ric in 
('AU000AC20095=YBAX','XS0088980494=MLIL','IT0003953350=HVBT')

So I declared a varchar variable and passing this string. In C# code, i am using the following function for this:

public string CreateRICList(RICObject[] ricobj)
		{
			StringBuilder sb = new StringBuilder();

			sb.Append("'");
			for (int i=0; i<=ricobj.Length - 1; i++)
			{
				sb.Append("''");
				sb.Append(ricobj[i].RIC);
				sb.Append("''");
				sb.Append(",");
			}
			string lstrics = sb.ToString();
			if (lstrics.EndsWith(","))
				lstrics.Replace(",","'");

			return lstrics;
		}

However, the string is not forming correctly. Is there any issue with the above code? Or is there any other method which I can pass the whole string at a stretch? Please help.

This is my stored procedure:

EXEC ('SELECT ISIN_Universe_Id,ISIN,RIC,DateCreated from ISIN_Universe
WHERE RIC IN ( ' + ''+ @LISTOFRICS + ''+ ')
AND DATECREATED > ''' + @PREVDAY + ''' AND DATECREATED < '''+@NEXTDAY+'''')

Thanks

The issue fixed. The string manipulation function refactored as follows:

StringBuilder sb = new StringBuilder();

			for (int i=0; i<=ricobj.Length - 1; i++)
			{
				sb.Append("'");
				sb.Append(ricobj[i].RIC);
				sb.Append("'");
				sb.Append(",");
			}
			string lstrics = sb.ToString();

			if (lstrics.EndsWith(","))
				lstrics = lstrics.Remove(lstrics.LastIndexOf(","),1);

			return lstrics;

Probably it will help somebody.

How to Find character in ArrayList

raju_shiva1-Jul-10 19:59

raju_shiva

1-Jul-10 19:59

Hi sir,
In VC++ we use str.Find();

How can we use the same in C#

Its working good in VC++
Here is the VC++ code i did:

CString strvalue;  // For Example strvalue is "A"	
CString strTemp;   //strTemp is lists in array
for()
{
 if(strTemp.Find(strvalue)==0)    // I will find "A" in array list
 m_ctrlCombo.AddString(strTemp);   // If found i will add it in Combo
}

I am trying the same in C#
But in C# we dnt have str.Find(),any other method to find it

Here is wat i am trying

ArrayList List = new ArrayList();

List.Add("AAA");
List.Add("AA");
List.Add("BB");
List.Add("BB");




for (int i = 0; i < List.Count; i++)
            
{
                        
 string value = List[i] as string;                
 if(value.Equals("AA"))
    comboBox1.Items.Add(value); 
}

but i am getting all the value from ArrayList.

Any idea

Thanks
Raj

You must try this out, if u really want to iterate :

ArrayList List = new ArrayList();

List.Add("AAA");
List.Add("AA");
List.Add("BB");
List.Add("BB");
foreach (string item in List)
{
     if (item.Equals("AA"))
          comboBox1.Items.Add(item); 
}

else, u can always go with this :

ArrayList List = new ArrayList();

List.Add("AAA");
List.Add("AA");
List.Add("BB");
List.Add("BB");
if (List.Contains("AA")
    comboBox1.Items.Add("AA");

If you you are using .net3.0 or higher you can use this:

C++

List<string> list = new List<string>();
list.Add("AAA");
list.Add("AA");
list.Add("BB");
list.Add("BB");

//The code from you might find a better way of doing it depending upon your requirements!
foreach (string found in list.FindAll(x=> x=="AA"))
    comboBox1.Items.Add(value);

The above code is one way if achieving what you want. The generic list (equivalent to a c++ template) has a few advantages, the list is strongly typed (in this case all elements are strings). Additionally the generic list has more methods allowing you to find stuff in the list over the old ArrayList. The only thing I'd say (and it's a drawback in the code snippet I've added) is that the predicate syntax looks a little weird if you aren't used to it: list.FindAll(x=> x=="AA")

See Generic List MSDN[^] for members of a generic lists if interested.

Not an answer to your question, but a suggestion.

An ArrayList is generally not recommended as every item has to be converted to/from a object. This boxing/unboxing is an unecessary performance hit and more importantly can make working with the items (and therefore the code) more complicated.

If the items are all of the same type then use List<T> (where T is the type of your object, so for the example you have given use List<string>. There are other collections in System.Collections.Generic and System.Collections.ObjectModel that you may find useful depending on what you are using the list for. I would recommend using the generic types where available or the ones that are type specific such as StringCollection.

If you have mixed classes that you want in a collection but they derive from a common base class or interface then you can have a collection of that eg: List<IMyBaseInterface>.

This just might be a typo, but you should be using System.Collections;

If this is right, then what version of the framework are using - remember Silverlight does not have an arrayList.
